HOSE-PATCH AND APPLYING-TOOL.

tures therein, novel means being provided for holding the meeting edges of the patch together, the patch being so constructed that it is well adapted to bear the strains imposed upon it, both by the adducting of the holding means, and by the internal pressure in the brake pipe.

Another object of the invention is to provide a tool of novel and improved con: struction, whereby a brake pipe patch may be tightened about the brake pipe, and secured thereto.

Another object of the invention is so to construct the tool that the same may, in a single operation, draw the meeting edges of the patch together, and secure them in place.

Another object of the invention is so to construct the tool that itmay engage the brake pipe patch in a novel manner during the adjustment of the patch.

Another object of the invention is so to construct the tool that it will be effective, in operation, not only to draw the meeting edges of the patch together, but, as well, to bend the retaining elements in such a man ner that they will retain together, the meeting edges of the patch.

With the above and other objects in view, the invention consists in the novel construction and arrangement of parts hereinafter described, delineated in the drawings, and specifically claimed, it being understood that changes, properly falling within the scope of what is claimed, may be made, without departing from the spirit of the invention.

Similar numerals of reference are employed to denote corresponding parts throughout the several figures of the drawings.

In the accompanying drawings,Figure 1 is a transverse section of a patch constructed in accordance with my invention, the tool for the manipulation of the patch being shown in elevation, and applied to the Specification of Letters Patent.

patch, the parts being in the positions which they will assume when the operation of drawing the meeting edges ofthe patch together, is about to be begun; Fig. 2 is a fragmental transverse section of the patch, the tool being shown in elevation, and applied to the patch, the parts being in the positions which they will assume, after the meeting edges of the patch have been drawn together and secured in the position to which they have been drawn; Fig. 3 is a fragmental side elevation of the patch, designed to show with particularity, one of the ribs which are secured to the meeting edges of the patch; Fig. 4: is a rear elevation of the tool, which, in Figs. 1 and 2, is shown applied to the patch for the manipulation thereof; Fig. 5 is a fragmental side elevation of one end of the tool, designed to show the manner in which the end of the tool is constructed to facilitate the operation of tightening and securing the patch; Fig. 6 is a fragmental perspective of a portion of a U shaped member which enters into the structure of the tool, the view being intended to show one of the hooks at the end of-the U shaped member, and to illustrate clearly, the groove which is located in the interior of the hook; and Fig. 7 is a side elevation of one of the pins which are passed through the ribs of the patch, in order to hold the meeting ends of the patch together.

The device forming the subject matter of this application, is intended primarily, although not exclusively, to be applied to the brake pipes of air brake systems, to heal accidental punctures therein. With a view to effecting this result, a split patch is provided, consisting of a body 1, preferably fashioned from thin sheet metal, and adapted to be disposed in the tubular form shown in Fig. 1.

Upon the meeting edges of the body 1 and upon the outer surface thereof, are secured ribs 2 and 2, a reinforcing strip 8, being lo- 'cated, if desired, upon the lower face of the body 1, beneath the rib 2. As indicated most clearly in Fig. 2, and as'denoted by the numeral 4 in Fig. 3, there are openings in the ribs 2 and 2, adapted to be alined, when, as shown in Fig. 2, the adjacent faces of the ribs are brought together. For a purpose to be described hereinafter, the outer face of the rib 2' is rounded and diminished in diameter as denoted by the numeral 5,

outline in Fig. 7 The pins, at one end,n1ay be taperedslightly as shown at 7,. and," at

. the other end, bent sharply upon themselves, or otherwise manipulated, to form heads 8.' vWhen a puncture is discovered inthe j brake pipe,"the; patch is placed over said i 15. "gaging the rib 2, and the tapered ends 7 puncture, a suitable cement, if desired, being first coated upon the interior of the body 1 ofthe patch,'or applieddirectly' to the brake pipe. henthe meeting ends of the body 1 are dra'wn togetl1er, the pins 6 are mounted in the openings 4, the. heads 8 enof' the pins being. bent to extend above the rib 2, as shown most clearly in Fig. 2. The

constructed tool into use.

- meeting ends of the body 1 will thus be.

secured together, any leakage fromthepuncture in the brake pipe being thereby prevented;

A hose patch constructed as above de- I scribed, may be manipulated in any desired manner and without calling any especially operationwill be facilitated greatly when the tool 'of the character hereinafter set forth isemployed. i

' The preferred .tool for the manipulation of thepatch comprises a handle 9, upon one face'ofwhich is adjustably mounted a block 10,"of substantially the same width as the handle. This block 10 isadjustably held in place by means of screws 11, adapted to recip'rocate in a longitudinally disposed slot 12 in the handle 9. In the lower face of the block 10 there is a transverse groove 21,

adapted to receive for pivotal 1nove1nent,.

the intermediate portion of U shaped member 18, the arms of which extend along the lateral edges of the handle 9, to project across shoulders 15 which outstand from the handle 9 adjacent the end 14 thereof, the arms o fthe U shaped member 18 terminating in hooks 19. The ends of the hooks 19 arerbeveled as denoted by the numeral '20,

while upon the under faces of the hooks are longitudinally extended grooves 22. By re ferring to Fig. 5, it will be seen that the end. 1 f the handlewhich outstands beyond the extensions is'notched as shown at.17, the lower edges of-the shoulders15 being outwardly extended to form lips 16.

p In using the tool to apply the hose patch, the beveled ends 20 of'thehooks 19aremade i to engage beneath the rounded portions 5 ,of the rib 2 the notch 17 in the end 14: of

V the handle9 being fitted upon the edge of the'rib 2. The seats formed bythe rounded portionsb of the rib 2, are adapted to receive thehooks 19,-to prevent the tool from sliding longitudinally of the patch: thus, the hooks are maintained in, such positions that the-ends of the pins 6 will be forced against However, the

the hooks. v The shoulders 15 are then made to bear against the heads 8 of the pins (3.

the lips 16 extending beneath the heads, thev heads bearing against the rib 2, and the tapered ends 7 of the pins being inserted into the openings 4 in the rib 2, all as 'shown to best advantage in Fig. 1. When the handle 9 is brought downwardly into the position shown in Fig. 2, the ribs 2 and 2 will, be drawn closely together, thus clamping the body 1 closely about the puncture in the brake pipe; hen the handle 9 is thus-moved from the position shown in Fig. 1 to that shown in Fig.2, the ends of the pins 6 will be advanced through the openings 4 in the ribs 2, said ends of the pins flexing, as shown in Fig. 2, and following the grooves 22 in the hooks19. The

" tool is fulcrumed upon the end 1 1, the shoul- 6, to hold the hose patch in position about the pipe.v Thus, in a single operation, the ends of the patch may be drawn together and secured in the position to which they have been drawn. Obviously, the screws 11 and slots 12 furnisha means wherebythe positions of the hooks 19 may be adjusted with respect to the end 14: of the handle 9, to accommodateribs 2 and 2, of different Having thus described the invention, what is Cll lI11Gd'1S2 1.
